All Hatteras hull bottoms are hand-laidin solid fiberglass with no coring

below the waterline.

Solid Hull Bottoms: Many competitors usecoring, either balsa or foam, below the water-line. This practice can expose boaters to long-term problems after a significant impact. If wateris left in a cored hull, it acts as a flexible splittingwedge and will continue to separate the innerand outer liner of the core structure. Hatterashull bottoms are hand-laid in solid fiberglasswith no coring below the waterline. Areas abovethe waterline where thru-hulls will be used arealso solid fiberglass, and heavy stress areas in thehull bottom — such as strut locations, rudderposts, shaft logs and engine beds — receiveintentional overlaps to provide additionalstrength. In the hull sides, Divinycell foam coring provides stiffness and reduced weight.

One-Piece Parts: Like its hulls, Hatteras’superstructures are laminated by hand as one-piece parts. The approach providesintegral strength, seamless construction and a clean appearance. Cockpits, bait centers and pulpits are all included in the moldingprocess, which eliminates unsightly caulk seamsthat appear on many competitors’ products.Hatteras utilizes non-absorbent Divinycellfoam core, as opposed to organic balsa, in itssuperstructures to deliver stiffness and a high

strength-to-weight ratio.

Resin Infusion and Vacuum Bagging:Hatteras utilizes state-of-the-arttechniques in the construction of decks,bulkheads and small parts. Many small partsare vacuum-bagged, a process in which piecesare saturated with a catalyzed polyester resin,sealed in a bag and compressed by a vacuum.Larger cored parts such as decks and bulk-heads are created using a process called resininfusion. Here, the Divinycell foam coring ispredrilled with tiny regularly spaced holes.Once the vacuum pressure is applied, resin is drawn through these holes, providing a pathway for the resin to saturate the outer skinsof the part. The result is a strong, thin, light-weight part with a smooth finish that featuresthermal and acoustic advantages over the plywood used by many competitors.

Engine Mounts: Engine beds are mountedwith anti-corrosive zinc-plated bolts to steelplates completely encapsulated in the fiber-glass stringers. By mounting the engine to the integrated fiberglass stringer networkinstead of exposed corrosive steel I-beams,force is uniformly distributed, thereby reducing the amount of engine vibrationbeing transferred throughout the boat.

Shoebox Fit: Hatteras featuresa precise hull-to-superstructure“shoebox” fit, provided by afour-part bonding process ofadhesive caulking, Monel screwsevery three inches, fiberglassbonding from the inside andreinforcement provided by a 11/4-inch 316L stainless-steel rub rail. The result is a unified hull and superstructurethat does not flex, separate or allow water intrusion.

Bulkheads: At least three major bulkheads — at the anchor

locker and forward and aft of the engine room — are installed

while the hull is in the mold to provide stiffness until

additional bulkheads and superstructure are installed on

the assembly line. These are tabbed into place using fixtures

to insure precise and consistent location in the hull.

Integrated Stringers: Hatteras stringers are filled with

closed-cell polyurethane foam to provide stiff longitudinal

support with no fear of water intrusion or rot that can occur

with the encapsulated wood used by many competitors. These

stringers, many of which are integrated into the hull mold

itself, work in conjunction with foam-filled athwartship

stiffeners to form a structural grid unmatched in the industry.

Fiberglass Tanks:All Hatteras fuel and

holding tanks are con-structed of fiberglass, rather

than corrosive aluminum thatsome competitors use. Hatteras fuel

tanks are the only ones in the industryto carry the approval of Underwriters

Laboratory, which requires rigorous construc-tion techniques, consistent pressure testing andquarterly inspections by UL representatives.Fuel tanks are constructed with a fire-retardantresin, and exposed surfaces are then coated with afire-retardant intumescent paint. Water tanks thatare constructed of fiberglass feature a resinapproved by the FDA for potable water and aresteam-cleaned for purity prior to installation.

Hatteras tanks feature a grid of fiberglassbaffles every 17 inches to reduce fluid movementand add strength. These baffles are laminatedand mechanically fastened to the tank, sealedwith a fiberglass reinforced adhesive, and thensealed again with fiberglass and resin. All fiber-glass tanks feature bronze tank plates and fittings.

Bronze Thru-Hulls:All primary thru-hull

fittings are constructed ofbronze in lieu of less durable

plastic to provide importantstrength and anti-corrosion proper-

ties. Hatteras mounts these thru-hulls in solid fiberglass versus the marine plywoodbacking used by some competitors. Brass seavalves are fitted to every underwater thru-hullfitting, and two stainless-steel hose clamps areused on all thru-hull connections below thewaterline and on all hoses with constant flow.

Environmentally Friendly Fuel Vent:Most builders use rectangular or square box-shaped fuel vents that allow excess fuel to spill overboard, into the waterways. Hatteras has designed spherical fuel vents (patentpending, to be introduced in 2005)that allow you to catch excess fuelin a reservoir, before returning it into the tanks. The result is a more attractive hull side, and more important,cleaner waterways.

Backing Plates: All stanchions and cleats are through-bolted to aluminum backing plates that are encapsulated into solid fiber-glass sections of the superstructure laminate.Bow rails connect to 1/4-inch backing plateswhile cleats are connected to 1/2-inch backingplates, all of which are drilled and tapped foreasy removal if the owner so desires.

QA Testing: Hatteras resins and gelcoats aresubjected to a 16-item test procedure upondelivery from our vendors to ensure quality.Burn tests of thru-hulls determine resin-to-glass ratios, ensuring the proper percentage as we strive for consistent strength without theaddition of weight. High-tech quality-controlsolutions, such as AIMS, are used to document,tabulate and eliminate quality concerns.

Anchor Chutes: All Hatterasanchor chutes are constructed

of heavy-gauge (3/8- and1/2-inch) 316L stainless

steel, versus the comp-etition’s thinner

“sheet metal.”

Rudder Shelves: High-tech ComputationalFluid Dynamic analyses and Finite Elementanalyses show that the rudder shelf area is amongthe harshest environments aboard any boat.That’s why Hatteras began constructing its rudder shelves with pultruded fiberglass in 2000.Pultruded fiberglass is an incredibly dense, strongand stiff material that will not corrode, rot, flex orbreak under strenuous use. Despite the obviousshortcomings of encapsulated plywood or balsa(lack of strength and potential rot) and aluminum(corrosion), Hatteras remainsthe only builder in its categoryto feature pultruded fiberglassrudder shelves.

Steering Gear: To maintainstructural integrity of the ruddershelf, custom-designed hexagonal retaining collars fit over all rudder shelf bolts to eliminatemovement. Standard lock washers used by thecompetition bite into the shelf material andeventually slip, allowing movement and damageof the steering gear. Stainless-steel rudder tie rodsare used exclusively versus mild steel tie rods,which deteriorate with saltwater exposure.

Crosscut Bearings: Traditional bearings uselongitudinal grooves to disperse a lubricating

water film. But as boat owners installlarger-horsepower engines and heaviershafts and propellers, this water canbe forced out of the bearing, leading tohigh-frequency noise and vibration at lowrpm that destroys the bearing over time.Hatteras has designed a new crosscut bearingthat uses crisscrossing grooves to disperse thewater, much like the tread of a tire does for acar. These grooves ensure a consistent film oflubricating water, giving longer life to your

bearings and less noise whiletrolling or cruising.

Recessed Shaft Logs:Hatteras recesses and fairs rudder and shaft logs to reducedrag. Hatteras uses solid fiber-

glass pads and overlays to provide maximumstrength at strut locations, rudder posts, shaftlogs and engine beds. Many competitors use a plywood backing.

Bronze Seals: Dripless propeller shaft and rud-der seals are designed in-house and constructed of bronze for strength, safety and durability. Bronze eliminates the possibility of a housing failure which is associated with plastic seal hous-ings that can melt with the loss of cooling water.

Mechanical Integrity

Sea Chests: All Hatteras models feature twin seachests, rather than dozens of individual pickup scoops,for all seawater intakes. These sea chests are recessedinto the hull and covered by Monel alloy screensthat rest flush with the hull bottom. Self-primingpumps for ship’s systems assure no loss in prime,even in rigorous offshore conditions. Not only dothe sea chests make maintenance easier for theowner or captain due to the centralized location ofseawater intakes, the removal of dozens of intakescoops improves the boat’s performance as well.

Fire Suppression: The Hatteras fire suppressionsystem is designed with automatic and manual activation, both of which trigger the system monitor’s

alarm. Once the system is acti-vated, all engines, generatorsand blowers are simultaneouslyshut down with the dischargeof the fire-fighting agent.

Air Conditioning: Hatterasinstalls enough chilled or

direct expansion air-conditioning capacity to providecomfort even in the most humid of environments.The system is designed so that each stateroom tenantcan adjust both the climate and fan speed individually.Many competitors tie systems together, preventingindividualized temperature settings.

Rudder Installation: Hatterasinstalls a locking collar andthrust washer on the rudderstock at the rudder port, as wellas the rudder shelf. This permitsthe hull bottom to carry theweight of the rudder to reducevibration and stress on the rudder shelf. Orcot rudder bearings are tougher than thetraditional rubber or plasticbearings that have a tendencyto deform over time, and do not afford excessive side-to-side movement.

Forced Air Induction System (FAIS): While many pleasure

craft builders employ induction fans to assist in the delivery of

air to the engines, Hatteras became the first builder to use them

exclusively for ventilation and combustion air with the introduc-

tion of the 80 Motor Yacht and 68 Convertible.

New Hatteras models feature hull designs that

lack the huge hull-side vents typical of tradition-

al product designs, relying solely on forced-

induction fans that draw cool air into the

engine room while under way, and push hot

air out of the engine room once back at the

dock. The FAIS virtually eliminates saltwater intrusion into the

engine compartment, and the lack of air-handling boxes in the

engine room vastly increases space outboard of the engines.

Underwater Exhaust: The newest Hatteras products feature

a passive exhaust system.At idle or low rpm, exhaust exits through

small elliptical holes in the transom. Once the engines achieve

approximately 1,400 rpm, the exhaust is scavenged through larger

vents in the hull bottom. This system reduces fumes in the cockpit

and buildup on the transom, as well as noise levels in the cockpit.

Tapered Rudder Bearings:Premature wear on all steering components can be minimized byreducing the amount of movementallowed. Hatteras is currently testinga tapered rudder bearing (patentpending) which uses the physicalweight of the rudder to continuallytighten itself intothe socket, keepingthe entire assemblysnug in place. Theresult: longer life for all your running gear.

Water Manifold Blocks:Hatteras models incorporatewater manifold blocks to distribute fresh water through-out the boat. The manifoldallows for fewer fittings andleak possibilities, and alsoenables the user to isolateand shut off a particular system to solve a problemwhile leaving the rest of theboat’s water system intact.

Shore Cord Protection:Hatteras uses shorelinepolarization transformers toprotect the boat’s electricalsystem against reverse polar-ity or loose shore-side neutralconnections — common marina-relatedelectrical problems. Stainless-steel and aluminuminlets with fuses provide a fire and corrosion-resistant mounting surface for shore cords, while a shore-line retractor with coiling tub keeps thecord clean and free from wear.

Bonding System:The Hatteras electricalbonding system connectsall metal componentswhich come into contact with seawaterand all non-current-carrying electrical

components together for increased personal safetyand to reduce the effects of electrolysis and galvaniccorrosion, increasing product life and ensuringretained value. Hatteras uses copper bonding strapsrather than the less effective stranded wire favored by some competitors.

UL®

UL-Approved: Virtually every electrical com-ponent that goes aboard a Hatteras is listed andapproved by Underwriters Laboratory. Fromthe breaker to the switch to the device itself,including all the fire-retardant wiring that links the chain, it’s all been inspected by athird-party service and certified as safe.

Finding Fault: Hatteras installs a GroundFault Interrupter on all lighting and receptaclecircuits throughout the boat. Most publishedstandards call for GFIs in head and galley receptacles only, but Hatteras uses them in all switches for additional safety. The GFI senses when a small current develops between

the ground and the conductor and tripsat approximately 5 milliamps, prevent-

ing electrocution hazards.

Dimmers: Hatterasinstalls dimmers through-

out the boat as standardequipment. Dual light

switches are placed at the salonentrance and at the companion-

way for convenience. Hatteras useselectrical junction boxes to enclose

connections on all AC circuits.

Smoke Detectors: Hatterasinstalls smoke detectors in everymain living area on each of itsyachts as standard equipment.While that may sound like commonsense, few other builders offer smokedetectors as standard.

Wiring: All wiring is tin-coated and sealed in an insulation jacket. These individuallytinned copper strands provide additional corrosion resistance for all electrical circuits.

Easy Maintenance: Hatteras wiring is color-coded and numbered at both terminalends, and is well documented in the owner’smanual for quick and convenient tracing.Wiring harnesses are tie-wrapped every 6 inches and secured every 18 inches, even when enclosed in wire trays and ducts.
